So, "the barrel that doesn't exist yet" showed up today. SPR profile 16" Grendel barrel from BA, and it's every bit as nice as the other Mk12 profile barrels I'm got from them. I had the lower, buttstock, VLTOR A5SR extension, and rifle spring sitting here from stock. I needed a few parts from DSG Arms to make a lower-minus-trigger, including a VLTOR A5-H2 buffer, so I ordered that stuff up once I had confirmation from BA that the barrel was real. I put the lower together and tossed a stock mil-spec trigger in it for now, until I can get a LaRue in it. BA pinned the gas block on there for me, which was a surprise - I like that.
While I was at work today, I thought about something - I have a 16" 300BLK rifle that I built up with a Precision Reflex FDE Gen III rail along time ago, just because. I've never like the setup, as a whole, it just never went all the way to a Mk12, and I never did anything with it after that... Shot well, but oh well.
YES! I ripped it down! I'll put a lightweight ALG 15" rail on that 300BLK, and I'll like it alot more like that. I'll have a "spare" PRI folding front sight until I can "Mk12 Mod 0" something in the future - but that's how I got here in the first place - parts stored.
I put that damn Ruger GSR flash hider on there for now, so I don't ding the barrel threads. The Allen Engineering hardware will be on this when I get it all wrapped up.
Here it is with the Mod 1:
I don't have the BCG or a charging handle, and there's ALOT of expensive PRI parts that I need to finish this, and that's gonna take MUCH time. In the meantime, if I raid a BCG and CH from a Grendel, and maybe raid an optic from a Grendel, I can shoot it next weekend and see how it does...
